Application filed October a, 1924. Serial no. 741,330.

To all whom it may oo ncem:

Be it known that I, HARRY W. KnANz, .a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and 8 State of Ohio,have invented a certain new and useful Improvement in Disk Wheels, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings. 1 This invention relatesgenerally to vehicle wheels and more particularly to a disk wheel havinga. demountable tire carrying rim.

The object of the invention is to provide an exceedingly simple methodof fastening a simple construction of rim upon-a simple form of disk.

Another object is to provide a wheel body particularly adapted forballoon tires and wheel of small diameters.

tion and in the manner of combining or arranging the same all of which,will be fully described hereinafter and set forth in th appended claims.

In the drawings forming a part of this specification Fig. 1 is a faceview of a wheel body and rim constructed in accordance with my inventionand Fig. 2 is a vertical sectional view of the same.

Referring to the drawings, A indicates a hub having a flan e A and abrake drum B is connected to t is flan e. A flange ring C is alsoconnected to thlshub flange and helps to secure the disk D'to the hub,there being hub bolts E employed to connect these parts together.

The disk D has a channeled peripheral portion D the inner side'of whichtermi- 40 mates in a flange D deep or high as the shoulders D.

The demountable tire carrying rim F has a central inwardly projectingportion F so With these objects in viewvthe inventionconsists in thevarious details of construc- The bottom of the channel D is not a truecircle but is forethe side 0 positethe valve d in cross sectionthat itwill fit snugl in t e half of the channeled periphery who issubstantially one half of a circle.

The other half of the rim contacts with the flange D when the rim isdropped down after the valve stem is inserted through the valve stemhole.

A bolt G is carried by the disk at a point opposite the shoulder D andupon this bolt is a wedge clamp H which engages the inwardly projectingcentral portion .13" ofthe rim F and a nut applied to the bolt G forcesthe clam laterally inwardly which securely fastens t e rim upon thewheel body for as the wedge clamp is screwed up the rim 'is forced.laterally against the flange D and the rim as a whole tensioned upon thewheel body being drawn down upon the semi-circular half at the same timethat it is moved laterallg into binding contact with the flange N Owingto the form of the disk and its zvided with a flan e at the inner sidethereof,

the-base of the c annel being foreshortened at one side, there-beingoutwardly projectmg shoulders at definite points opposite theforeshortened portion, of a demonntable tire carrying rim having acentral inwardly-projecting. portion seating in the channeled periphery,and a clamplng wedge carried by the wheel body and adapted to engage theand secure the same upon the wheel 2'. The combination with ademountable tire carrying .rim having tire engaging flanges and acentral inwardly projecting portion, said rim having a valve. stem holeto receive the valve stem of a tire, of a disk havin a channeledperipheral portion, said perip ery having an outwardly projectingshoulder in line with said valve stem hole, and outwardly projecting atpoints upon opposite sides of the first named shoulder, said peripherybeing foreshortened at a 5 point opposite the valve stem hole, a boltcarried by said disk at said foreshortened portion, a wedge clamparranged thereon and contacting with said rim, and a nut for forcing theclamp into engagement with said rim. 10

In testimony whereof, I hereunto affix my signature.
